This year’s Martin Luther King Jr Day featured the usual cast of civic and faith leaders engaged in acts of community service, but it also included an unlikely actor: the International Brotherhood of Teamsters.

The union’s “Deliver on the Dream” campaign sought to build on the true legacy of Martin Luther King Jr’s struggle for economic and racial justice. All over the country and across more than a hundred thirty different worksites, Teamsters mobilized with parking lot rallies and petitions to demand that United Parcel Service (UPS) make MLK Day a paid holiday, in accordance with a resolution passed at the last Teamster convention. They also demanded the company end two-tier jobs, create more full-time jobs, and pay part-time employees a living wage.

“Dr King’s dream is still unfulfilled when we still have part-timers working for poverty wages with no access to full-time jobs. By fighting to make MLK Day a paid holiday UPS Teamsters are saying it is time we all be treated with respect,” explained Eliza Schultz, a part-time package handler from Chicago.
